- Also see Dosage Modifications and Cautions
Contraindications
None
Cautions
Also see Dosage Modifications
May cause severe drug-induced liver injury with fatal outcome (see Black Box Warnings); obtain liver function tests (ALT, AST, and bilirubin) before initiation of therapy and monitor at least every 2 weeks during first 2 months of treatment; thereafter, monitor monthly or more frequently as clinically indicated; monitor liver function tests weekly in patients experiencing elevated liver function tests until improvement to less than 3 times the ULN or baseline; temporarily hold and then reduce or permanently discontinue therapy depending on severity and persistence of hepatotoxicity as manifested by elevated liver function tests or hepatocellular necrosis
Increases risk for hemorrhage; discontinue therapy for severe or life-threatening hemorrhage
Increased risk of infections reported; most common infections include urinary tract infections, nasopharyngitis, mucocutaneous and systemic fungal infections and pneumonia
Increases risk for HFSR/PPES and rash; a higher incidence of HFSR reported in Asian patients; interrupt and then reduce or discontinue regorafenib depending on severity and persistence of dermatologic toxicity
Hypertension may occur, typically during the first treatment cycle; do not initiate therapy unless blood pressure is adequately controlled; monitor blood pressure weekly for first 6 weeks of treatment and then every cycle, or more frequently, as clinically indicated; temporarily or permanently withhold therapy for severe or uncontrolled hypertension
Myocardial ischemia and infarction observed in clinical trials; withhold regorafenib for new or acute cardiac ischemia/infarction and resume only after resolution of acute ischemic events
One case report of reversible posterior leukoencephalopathy syndrome (RPLS) reported (1 of 1100 treated patients); discontinue therapy if RPLS occurs
Discontinue therapy if gastrointestinal perforation or fistula occur
May impair wound healing (class effect of VEGFR inhibitors); complications can occur in patients who receive drugs that inhibit the VEGF signaling pathway; discontinue at least 2 weeks before scheduled surgery; do not administer for at least 2 weeks following major surgery and until adequate wound healing; safety of resumption of drug after resolution of wound healing complications not established; discontinue therapy in patients with wound dehiscence
Embryo-fetal toxicity likely if taken while pregnant (see Pregnancy & Lactation)
Drug interactions overview
-
Strong CYP3A4 inhibitors
- Coadministration with strong CYP3A4 inhibitors increases regorafenib plasma concentrations, decreased active metabolite (M-2 and M-5) plasma concentrations, and may increase toxicity
- Avoid concomitant use of regorafenib with strong CYP3A4 inhibitors (eg, clarithromycin, grapefruit juice, itraconazole, ketoconazole, nefazodone, posaconazole, telithromycin, and voriconazole)
-
Breast cancer resistance protein (BCRP) substrates
- Coadministration with a BCRP substrate increases the BCRP substrate plasma concentrations
- Closely monitor for signs and symptoms of exposure-related toxicity of the BCRP substrate (eg, methotrexate, fluvastatin, atorvastatin)
- Consult the concomitant BCRP substrate product information when considering administration of regorafenib
-
UGT substrates
- Regorafenib competitively inhibits UGT1A9 and UGT1A1 substrates
Pregnancy & Lactation
Pregnancy
Based on animal studies and mechanism of action, fetal harm may occur when administered to a pregnant woman
There are no available data on use in pregnant women
Advise pregnant women of the potential hazard to a fetus
Animal data
- Administration of regorafenib was embryolethal and teratogenic in rats and rabbits at exposures lower than human exposures at the recommended dose, with increased incidences of cardiovascular, genitourinary, and skeletal malformations
Contraception
- Females: Use effective contraception during treatment and for 2 months following the final dose
- Males: Advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 2 months following final dose
Infertility
- There are no data on the effect on human fertility
- Results from animal studies indicate that regorafenib can impair male and female fertility
Lactation
There are no data on the presence of regorafenib or its metabolites in human milk, the effects of regorafenib on the breastfed infant, or on milk production In rats, regorafenib and its metabolites are excreted in milk
Because of the potential for serious adverse reactions in breastfed infants from regorafenib, do not breastfeed during treatment and for 2 weeks after the final dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
